In this whitepaper, purchasers of enterprise storage have historically dealt with an upgrade cycle that was expensive, disruptive, inherently risky, time-consuming and occurred roughly every three-to-five years. In 2015, Pure Storage challenged customer preconceptions about the enterprise storage upgrade cycle with its Forever Flash Program which, combined with the company’s technology architecture, creates what is referred to as Evergreen Storage.

This IDC White Paper assesses Pure Storage’s Evergreen Storage model, reviewing both existing approaches and this new approach in terms of the impacts on customers and their business and financial implications.
